In this study, functional strains from the natural environment such as fermented pig manure were isolated and identified by preliminary screening and rescreening. Among them, strains such as Bacillus subtilis, Bacillus pumilus, Brevibacillus laterosporus, and Proteus mirabilis had a particularly strong ability to inhibit the release of ammonia gas. Through many repeated trials, we confirmed that this bacterial agent could adapt to environments containing water and grow normally. A deodorant was developed and tested on pig farm sewage. Further, the appropriate dosage of the composite microorganism bacterial agent and the change in various indices of the sewage with treatment time were verified.
